the like, or in the building of any class of structure where an overheadtramway could be used to advantage.

The primary object of this invention is to provide an overheadtravelling system that is capable'of carrying loads and depositing themat any and all points within a prescribed three dimensional space.

One advantage resides in the fact that a load may be carried from onepoint to another point either above or below in the same plane or it maybe carried in a direction perpendicular to this plane or it may becarried in a third direction perpendicular to the lastmentioned plane.Or still further it may be carried in all three directions at once. Thisprovides a three dimensional movement which is the ultimate and definesspace itself.

A further advantage lies in the arrangement of parts. By introducing twotravellers properly spaced apart on the same supporting line it iseasily seen that all twisting of load lines is eliminated. Further thanthis, the points of suspension are separated on the supporting cable anddo not cause excessive stresses as the single point of suspension does.Then by combining this two point suspension with another suspportingcable identical in detail, I obtain results that are new to the art ofcableway manipulation,

and give a wider range of application than has heretofore been availablefor overhead cableways.

In such structures as clams it is particularly necessary to have asystem that can pick up a load at one point and transfer it to anotherwithout any pulling and hauling by the men as is customary with thepresent equipment. It is therefor obvious that the application of thisinvention which transports from any point to any point within aprescribed space, would produce better results both from an efficientand an economical point of view.

A still further advantage lies in the central control system, whichpermits one man to control the three movements from one point.

The above advantages, together with those that may subsequently bedeveloped in the descriptions, constitute my invention, which is morefully explained by reference to the drawings, in which:

Figure 1 shows my idea as it would be used in building a dam;

Figure 2 shows an enlarged View of the main traveller;

Figure 3 shows an enlarged view of the hook; and

Figure 4 is a diagrammatic view showing how the outhaul and inhaul linesare hooked up.

Referring now in detail to the drawings, in Figure 1 an ordinary dam Ais shown as under construction. Spanning the canyon at an elevationsufliciently high to permit of manipulating the underslung cablessatisfactorily, are two main cables 1 and 2 which are supported at 1each side by suitable towers 34:-5 and 6, and anchored at each'end as at7-89 and 10. The main cables 1 and 2 are substantially parallel but maybe used within certain limits even if they are divergent or convergentas the case may be. Carried on cable 1 are two travellers 11 and 12which are designed to ride the main cable and carry the load cable 13,which load cable has its origin at the hoist drum 14, and is threadedthrough a sheave block 15 suitably anchored in front of the hoist, thenthrough another sheave block 16 fixed to the anchorage 7, on throughanother sheave block 17, which is mounted on the tower 3, when it issuspended under the main cable 1, and carried by the standard carriers76.

After passing through a sheave 19 in the traveller 11, the cable 13continues on through a sheave 20, pivotally attached to the hook 21which is the carrying hook, and passes up to another sheave 22 which iscarried by traveller 12. After passing over this last named sheave thecable 13 is suspended again under the main cable 1 by the carriers 76and continues on over the top of the tower 4: to the anchorage 8 whereit is dead ended.

An identical construction is provided for main cable 2 which carries.two travellers 23 and 24 which are designed to ride the main cable andcarry the load cable 25. Said load cable has its origin at the hoistdrum 26 and passes over a sheave 27 which is suitably anchored in frontof the hoist. From this sheave it goes over another sheave 28 fixed tothe anchorage 10 and continues on over another sheave, not shown on theopposite side of tower 6. From this point it is suspended under the maincable and carried by the carriers 76 to the traveller 23 where it passesover the sheave 29 carried by said traveller. From here the cable 25continues on through a sheave 30 which sheave is pivotally attached tothe hook 21 and passes up to another sheave 31 carried by the traveller24. From here on it is suspended under the main cable 2 and carried bythe carriers 76 until it passes over the top of the tower 5 and on tothe anchorage 9 where it is dead ended.

The aforementioned structure provides a lifting and a lateral movement,but will not produce a travelling movement along the main cables.

In order to get this movement which furnishes the third dimensionheretofore mentioned, there is provided an inhaul line 32, which has itsorigin at the hoist drum 33 from which it passes over a sheave 34,suitably anchored in front of the hoist, and continues through thesheave 35, suitably fastened to the tower 6, on tothe traveller 23 towhich it is fastened.

The outhaul line 36 starts at the hoist drum 37 and passes through asheave 38 suitably anchored in front of the hoist, from there it passesover the canyon and through the sheave 39, which sheave is fastened tothe tower 4. After passing through sheave 39 it continues back under theload cable and is fastened to the traveller 12.

To complete the control system a hook-up between the two main cables isaffected in the following manner: between the travellers 11 and 12 thereis provided a connecting cable 41, which regulates the distance betweenthem and also serves as a connecting link in conneetin the inhaul andouthaul lines. Connected to the opposite side of the traveller 11 isanother cable 42, which provides another link in the connection, whichcable is carried through a sheave 43 fixed to tower 3. From there iscrosses back over the canyon and passes through another sheave 44 fixedto tower 5. After passing through the last named sheave it passes alongunder the load cable and is finally attached to traveller 24. Betweenthe travellers 23 and 24 there is provided a cable 45, one end of whichis attached to 23 and the other end to 24. This last named cableprovides the final link in the control system which is best shown inFigure 4.

Here it can be observed that when the hoist drum 33 draws in on thecable 32 the travellcrs 23-24-11 and 12 are moved simultaneously anequal distance in the same di rection, and that the same amount taken inby drum 33 must be payed out by drum 37. This would constitute aninhaul, whereas by reeling in the drum 37 an outhaul movement would takeplace. just the reverse of the foregoing action. Suppose, for example, abundle was held by the hook and it was desired to place it in the circledesignated by B on the farther corner of the dam. The outhaul would besimple, but to place it on the exact spot would require something morein the line of cableway equipment than now exists. My invention providesthis. Movement transverse to the cables 1 and 2 is accomplished bydrawing in on the load cable 13 and paying out on the load cable 25, andvice versa, Transverse movement of the bundle 50 is also eifeeted bypaying out on one load cable only, or drawing in on one only. By drawingin both load lines equally, a raising movement is accomplished,-alowering is just the reverse. Thus the bundle 50 can be moved back to aline crossing the spot B, by taking in on line 36 and paying out on line32. Then, assuming that the spot is to the right of the bundle, slackcould be fed into cable 25, and if the bundle dropped too much as it wasbeing moved, the cable 13 could be taken up until the bundle wasdirectly above the spot. Now a paying out of both cables 13 and 25 atthe proper relative speeds, will lower the bundle directly upon thespot.

Figure 2 shows the structure of the travellers which are provided withtwo grooved wheels and 61, designed to ride the supporting cables 1 or2. I have shown the cable 1 in Figure 2. A third wheel 64. in sheave 19is similar to the other two and is located below the supporting cable insuch a manner that it carries the load line 13. Attached to each side asat 67 and 68 are the inhaul line 42 and the outhaul line 41. Alsoattached to each side as at 72 and 73, are the small auxiliary lines 7 5and 75 respectively. These serve as means for limiting the distancebetween adjacent carriers 7 6.

Figure 3 shows an enlarged hook 21 with its attendant structure.Pivotally mounted as at and 81 on the hook structure are the two sheaves20 and 30, and rotatably mounted within these sheaves are two wheels 84and 85 respectively, which wheels are adapted to carry the load cables13 and 25 respectively.

The foregoing description pertains to only one application of myinvention, and knowing there are many more cases where it could beapplied, I understand that I am entitled to such modifications andrefinements that do not depart from the spirit of the foregoingdescription, nor the appended claim.

It should be noted that the load lines 13 and 25 are run through thestandard carriers 7 6 which are held equally spaced along the maincables 1 and 2 by the small auxiliary lines 75 and 75. The spacingbetween the carrier 76 does not exceed a predetermined limit, otherwisethe load lines Would sag between carriers. Suflicient carriers areprovided for each line 13 and 25 to be spaced at proper distance acrossthe entire length of the lines should the travelers 11 and 12 be movedentirely thereacross.

I claim:

A cableway comprising two main cables anchored at their ends, a carriermounted on each cable, a load cable carried by each carrier, a hookmovably supported between the two load cables, and a carrier-movingcable extending along the length of one main cable and then extendingdiagonally across from the end of the first main cable to the oppositeend of the other main cable and then extending throughout the length ofthe second main cable.
